Following a suggestion by Grant (Struth) I tried Discogs for a Joe Jackson Trio double album. It's selling for £24 on Amazon, but I've just bought it for 9 quid inc postage from Discogs. And this is for "brand new sealed". Seems too good to be true. Is it likely to arrive in a knackered sleeve, or even arrive some time after Christmas?

Has anybody had any good/bad experiences dealing with them?
